Ketoconazole has been widely used as an antifungal drug that is formulated as tablets, cream and overthecounter
ketoconazole shampoo. The aim of this research was to study and to standardize an ultraviolet spectrophotometric (UVS)
method, potentiometric and a high performance liquid chromatographic (HPLC) method for the determination of
ketoconazole in commercially available Oromycosal® tablets. These three methods were compared and discussed with
respect to their sensitivity, selectivity and readyapplicability in routine analytical work. Absorption spectra and spectrophotometric determinations were carried out on the UVS spectrophotometer. Investigated concentrations were in range from 0.003 to 0.02mg?dm3.
The absorbance was measured at 224 nm. In potentiometric titrations glass and saturated (KCl) calomel electrode were used. HPLC analyses of ketoconazole were carried in the presence of econazole as internal standard. It can be concluded that the described methods are simple, fast and reliable for determination of ketoconazole in pharmaceutical preparations. The preparation of the samples is easy, the excipients do not interfere in the methods, so they can be used in routine quality control analysis
